Arduino Nano is a compact
microcontroller board based on the ATmega328P, offering 14 digital I/O pins, 8
analog inputs, and a USB interface for easy programming. It is ideal for
embedded applications, prototyping, and wearable projects.
Description
The Arduino Nano is a compact,
breadboard-friendly development board based on the ATmega328 microcontroller,
which is the same microcontroller used in the Arduino Uno, but in a smaller
form factor.
Key Features of
the Arduino Nano
1. Microcontroller
The Arduino Nano is built
around the ATmega328 microcontroller, which provides:
32KB of flash memory (used to store the program),
of which 2KB is used by the bootloader.
2KB of SRAM (for runtime variables).
1KB of EEPROM (for permanent data storage).
It is breadboard-friendly, meaning it can be
plugged directly into a breadboard for prototyping, which is not possible
with larger boards like the Arduino Uno.
2. Pins
The Arduino Nano has 30 pins
in total, including:
14 digital input/output pins, of which 6 can be
used as PWM (Pulse Width Modulation) outputs.
8 analog input pins (A0-A7).
2 serial communication pins (TX, RX).
SPI and I2C communication support.
Mini USB port.
The Nano uses a mini-USB or micro-USB connector,
whereas the Uno uses a standard USB-B connector.
3. Power Supply
The board can be powered in
two ways:
Through the USB connection (5V).
Through an external power supply (5-12V) via the
VIN pin.
The onboard voltage regulator ensures stable 5V
and 3.3V outputs.
